Perhaps the worst part of this story is the fact that police had ordered the Rana Plaza building to be shuttered a day before the collapse, due to deep, dangerous-looking cracks in the building’s structure. But the garment factory owners on the fourth floor of the building ignored the police instructions and ordered their more than 2,000 workers back inside to sew.

According to the CBC, the fourth-floor garment factories made clothes for American retailers including Walmart, The Children’s Place, Dress Barn, and Benetton.
